[glib: 3/5] gio/tests: add a test for document portal use when launching flatpaks

[Philip Withnall <pwithnall src gnome org>]

    gio/tests: add a test for document portal use when launching flatpaks
    
    We can't use session_bus_down() in the test since gdocumentportal.c
    holds a reference to the session bus connection, preventing it from
    being finalised.
